    • ActiveRDF: Object-oriented semantic web programming 

      Oren, Eyal; Delbru, Renaud; Gerke, Sebastian; Haller, Armin; Decker, Stefan (Association for Computing Machinery, 2007)
      Object-oriented programming is the current mainstream programming paradigm but existing RDF APIs are mostly triple-oriented. Traditional techniques for bridging a similar gap between relational databases and object-oriented ...
    • Aiding the Data Integration in Medicinal Settings by Means of Semantic Technologies 

      Nováček, Vít; Handschuh, Siegfried (Semantic Technology Institutes International, 2007)
      The paper introduces basic features of a novel ontology integration framework that explicitly takes the dynamics and data-intensiveness of many practical application scenarios into account. We motivate our research partially ...
    • Dynamic Integration of Medical Ontologies in Large Scale 

      Nováček, Vít; Handschuh, Siegfried (ACM Press, 2007)
    • Dynamic Querying of Mass-Storage RDF Data with Rule-Based Entailment Regimes 

      Krennwallner, Thomas; Martello, Alessandra; Polleres, Axel (Springer, 2009)
      RDF Schema (RDFS) as a lightweight ontology language is gaining popularity and, consequently, tools for scalable RDFS inference and querying are needed. SPARQL has become recently aW3C standard for querying RDF data, ...
    • Extending Community Ontology Using Automatically Generated Suggestions 

      Nováček, Vít; Dabrowski, Maciej; Kruk, Sebastian Ryszard; Handschuh, Siegfried (AAAI Press, 2007)
      In this paper we propose an ontology (formal knowledge base) creation methodology based on integrating external ontologies into the one developed by a community of the do- main experts. We present the MarcOntX agent, a ...
    • Handling heterogeneity in RosettaNet messages 

      Haller, Armin; Kotinurmi, Paavo; Vitvar, Tomas; Oren, Eyal (2007)
      We present a semantic B2B gateway based on the WSMX se- mantic Service-Oriented Architecture to tackle heterogeneities in RosettaNet messages. We develop a rich RosettaNet ontology and use the axiomatised knowledge and ...
    • Imprecise Empirical Ontology Refinement: Application to Taxonomy Acquisition 

      Nováček, Vít (INSTICC, 2007)
      The significance of uncertainty representation has become obvious in the Semantic Web community recently. This paper presents new results of our research on uncertainty incorporation into ontologies created automatically ...
    • Infrastructure for Dynamic Knowledge Integration -- Automated Biomedical Ontology Extension Using Textual Resources 

      Nováček, Vít; Handschuh, Siegfried; Davis, Brian (Elsevier, 2008)
      We present a novel ontology integration technique that explicitly takes the dynamics and data-intensiveness of e-health and biomedicine application domains into account. Changing and growing knowledge, possibly contained ...
    • Leveraging Ontologies, Context and Social Networks to Automate Photo Annotation 

      Monaghan, Fergal; O'Sullivan, David (Springer, 2007)
      This paper presents an approach to semi-automate photo an- notation. Instead of using content-recognition techniques this approach leverages context information available at the scene of the photo such as time and location ...
    • m3pl: A Work-FLOWS ontology extension to extract choreography interfaces 

      Haller, Armin; Oren, Eyal (2006)
      Cross-organisational interoperability is a key issue for success in B2B e-commerce applications. To achieve this interoperability, choreography descriptions are necessary that describe how the business partners can cooperate. ...
    • A Non-traditional Inference Paradigm for Learned Ontologies 

      Nováček, Vít (CEUR Workshop proceedings, 2007)
    • On the Ostensibly Silent 'W' in OWL 2 RL 

      Hogan, Aidan; Decker, Stefan (Springer, 2009)
      In this paper, we discuss the draft OWL 2 RL proable from the perspective of applying the constituent rules over Web data. In particular, borrowing from previous work, we discuss (i) optimisations based on a separation ...
    • Ontologising Interaction Behavior for Service-Oriented Enterprise Healthcare Integration 

      Sahay, Ratnesh; Fox, Ronan; Hauswirth, Manfred (IEEE, 2008)
    • Ontology label translation 

      Arcan, Mihael; Buitelaar, Paul (Association for Computational Linguistics, 2013-06-09)
      Our research investigates the translation of ontology labels, which has applications in multilingual knowledge access. Ontologies are often defined only in one language, mostly English. To enable knowledge access ...
    • OTTO - ontology translation system 

      Arcan, Mihael; Asooja, Kartik; Ziad, Housam; Buitelaar, Paul (CEUR-WS.org, 2015-08-11)
      To enable knowledge access across languages, ontologies that are often represented only in English, need to be translated into different languages. For this reason, we present OTTO, an OnTology TranslatiOn System, which ...
    • Processing ontology alignments with SPARQL 

      Polleres, Axel (IEEE, 2008)
      Solving problems raised by heterogeneous ontologies can be achieved by matching the ontologies and processing the resulting alignments. This is typical of data mediation in which the data must be translated from one ...
    • Quantified equilibrium logic and hybrid rules 

      Polleres, Axel (Springer, 2007)
      In the ongoing discussion about combining rules and Ontologies on the Semantic Web a recurring issue is how to combine first-order classical logic with nonmonotonic rule languages. Whereas several modular approaches to de- ...
    • A rule system for querying persistent RDFS data 

      Krennwallner, Thomas; Martello, Alessandra; Polleres, Axel (2009)
      We present GiaBATA, a system for storing, aggregating, and querying Semantic Web data, based on declarative logic programming technology, namely on the dlvhex system, which allows us to implement a fully SPARQL compliant ...
    • SAOR: Authoritative Reasoning for the Web 

      Hogan, Aidan; Harth, Andreas; Polleres, Axel (Springer, 2008)
      In this paper we discuss the challenges of performing reasoning on large scale RDF datasets from the Web. We discuss issues and practical solutions relating to reasoning over web data using a rule-based approach to ...
    • Scalable Authoritative OWL Reasoning on a Billion Triples 

      Hogan, Aidan; Harth, Andreas; Polleres, Axel (2008)
      In this paper we present a scalable algorithm for performing a subset of OWL reasoning over web data using a rule-based approach to forward-chaining; in particular, we identify the problem of ontology hijacking: new ...
